Limit Output Of Python Traceback

The aim of this playbook🏁 is to limit output in python’s stack trace.

1. steps/notes

• traceback is another name for stack trace
• raise keyword returns the whole trace, which is a bit too much for this instance

Enter New Section Name (e.g. 00 SnowBar): Snow
Traceback (most recent call last):
  File ".\helpers\createSections.py", line 18, in <module>
    createSections()
  File ".\helpers\createSections.py", line 13, in createSections
    raise ValueError(
ValueError: The first 2 characters need to be a sectionID, e.g. 66

• adding sys.tracebacklimit = 0, I am getting only the last line

ValueError: The first 2 characters need to be a sectionID, e.g. 66

• this is exactly right!

2. example

• just a simple input validation instructing to start a section name with a double-digit

def _validate_and_capitalize(name, sectionFolders):
    sys.tracebacklimit = 0
    if not re.match(r"\d\d\s.*", name):
        raise ValueError(
            f"The first 2 characters need to be a sectionID, e.g. 66")
